GENERAL PRECAUTIONS
•Do not use bromine based products in the pool. Use of bromine will void the
warranty on your chlorine cell.
•It is the pool owner's responsibility to ensure water is regularly tested and balanced.
Your local pool professional can advise you on appropriate testing frequency and
balance criteria in your area.
•When taking a water sample for testing, make sure to use an appropriate water
sample bottle (available from most pool shops), and ensure the sample is as fresh
as possible. Avoid exposing the sample to heat and/or sunlight while in transit.
•Do not use old soft drink bottle for water samples as this may produce highly
inaccurate test results.
•Where calcium hardness of the pool / spa water exceeds 200ppm, the water must
be balanced according to the Langlier Index to ensure water is not scale forming.
Consult you local pool professional for advice.
•Do not assume the chlorinator is faulty if a chlorine test reveals a low free chlorine
level. There are many factors that relate to chlorine demand in the water. Refer to
the troubleshooting guide in this manual for more information
•Regular manual 'super chlorination' or 'shock dosing' may be required in pools
particularly where chlorine demand or bather load is high.
•Test salt level before calculating your salt addition requirements, even on a new
installation – especially where liquid chlorine had been used previously.
•ree chlorine levels above 4.0ppm may void manufacturer warranties on your
equipment.
•Unnecessarily high salt levels may contribute to corrosion of pool and spa
equipment.
•Only use original and proprietary Pool Lab Reagent Bags.
•Never add pool or spa chemicals directly to the skimmer as this can lead to false pH
and chlorine readings on the ASP, and therefore incorrect chemical dosing.
•Pool L b recommend the use of Cy nuric Acid (St bilizer) t concentr tion
of between 50-80 ppm for outdoor pools to help protect chlorine in the w ter
from destruction by sun light

IMPORTANT SAFETY INSTRUCTIONS
➔Read all sections of this owner's manual before installing or operating the
equipment
➔Do not allow children or any unqualified person to operate or perform any
maintenance on this equipment.
➔Always ensure free chlorine level is maintained above 1.0ppm and avoid free
chlorine levels above 3.0ppm
➔Ensure water is regularly tested by a pool professional, and ensure all aspects of
water balance are properly maintained.
➔Do not allow bathers to use pool or spa if the free chlorine level is above 8.0ppm
➔OR SPA ONLY INSTALLATIONS: Proper sanitation requires the spa be
periodically drained completely. As a guide, the number of days between complete
spa drainage should be equal to the volume of the spa in litres, divided by 10 times
the maximum number of daily spa users
Health and Hypothermia Warnings
➔People with medical conditions should consult a physician before entering pool or
spa water
➔Maximum spa water temperature is 40 degrees C
➔Bathing time in spa water at (or near) 40 degrees C should not exceed 15 minutes
6

Hydrochloric (Muri tic) Acid W rnings
➔Read warnings on the label. Do not allow acid to come in contact with skin, eyes or
mouth, and follow directions on label if accidental contact occurs.
➔Hydrochloric acid is highly corrosive, and will corrode metallic surfaces.
➔General advice for accidental skin or eye contact with Hydrochloric Acid is to flush
continuously with fresh running water for at least 15 minutes, and remove any
contaminated clothing. Seek immediate medical attention.
➔Hydrochloric Acid does produce dangerous fumes. These fumes are highly irritating
to skin, eyes and airways, and can also damage equipment. Always ensure the
area is well ventilated when handling acid.
➔Always wear protective clothing when handling acid or servicing the acid dosing
system. Acid resistant gloves, eye protection or face shield, boots and a suitable
respirator are recommended.
Note: a Type E filter approved to EN141, European Standard for Gas Filters is
suitable for Hydrochloric acid fumes
➔Service acid dosing pump at least every 12 months
➔When diluting acid, always add acid to water. Never dd w ter to cid.
➔Store acid in a cool, dry, and well ventilated place away from sources of moisture.
Keep away from incompatible materials, such as oxidizing agents, organic
materials, metals and alkalis.
Acid Dosing System Warnings
➔or installations where an acid leak could result in damage to property such as
flooring or nearby equipment, or where a leak may result in a safety hazard, the
drum must be located within an additional containment vessel with a capacity no
less than 200% of the acid drum volume. The containment vessel must be made
from a plastic suitable for containment of hydrochloric acid eg. High Density
Polyethylene (aka. HDPE) and should ideally be located directly below the acid
pump and feed tubes so that it may catch any potential leaks from acid feed tubing
and fittings. This will minimize the risk in the event of a leak.
➔The area around the acid dosing system, including the storage drum and feed tubes
must be inaccessible to children, animals and other unauthorised persons.
➔The acid drum MUST NOT BE located in direct sunlight as heat will cause the drum
to pressurize, resulting in a safety hazard and increased risk of leakage.
➔or a SPA ONLY system, acid drum volume must be limited to 5 Litres.
➔The acid drum and acid dosing system components must be located in a well
ventilated area (preferably a shaded outdoor area) where there is minimal risk of
damage to persons and/or property in the event of an acid leak.
➔or indoor installations the installer must complete a risk assessment and discuss
plans with the property owner for minimizing risks to persons and property.
➔All elements of the acid dosing system must be regularly inspected to ensure it is in
safe working order. Components must be replaced when degradation is evident, as
per the instructions.
oolpower Australia ty. Ltd. will not be liable for damage where a duty of care has not
been demonstrated with respect to the installation of this equipment or its ongoing
maintenance.

INTRODUCTION
The Pool Lab ASP (Auto Sampling Photometer) utilizes proven photometric technology
and a patented analysis technique to automate control of the pH and free chlorine levels in
pools and spas. It takes the guesswork out of balancing and treating your pool water, and
through automation significantly reduces the requirement to regularly handle dangerous
chemicals around your pool or spa.
The need to regularly test water, balance pH, and manage chlorine dosage is fundamental
in maintaining healthy balanced water. Bather load and environmental impacts are highly
dynamic, therefore guessing the dosage requirements to control these parameters is not
always sufficient. The chlorine demand in a pool can vary enormously with changes in
bather load, water temperature, debris, weather, and the application of pool covers.
Typically on a domestic pool, the Pool Lab ASP will perform three pH and free chlorine
tests per day, and the results of these tests are compared with the user defined targets for
these parameters. If a correction is required, the ASP will automatically calculate and
administer the required dosage of chlorine and acid, and will also automatically track and
account for changes in the chlorine and acid demands in your pool or spa.
Where a pool and spa combination exists, a flow switch on the spa suction line allows the
ASP to establish which volume of water it is treating, and adjust dosage accordingly. The
ASP will also not deliver acid while the spa is in use.
The Pool Lab ASP will ensure your pool water is correctly sanitized with chlorine, and the
pH maintained. Other less volatile water balance parameters such as Total Alkalinity,
Calcium Hardness and Stabilizer level must be checked manually, and adjusted by either
yourself or your local swimming pool professionals.
Over 20 years of ground breaking research and development have led to this unique
Australian product, with pool owner's globally enjoying the benefits of Pool Lab's
innovative technology.
Welcome to Pool Lab!

OVERVIEW
HOW THE POOL LAB ASP WORKS
This flow chart is a basic representation of the ASP test sequence.
NOTES:
–Acid feed will be halted if filter pump is turned off, or low flow is detected.
–If a large increase in pH is detected, acid feed will be paused for 24 hours.
–Safety limits prevent over feeding of acid, based on pool / spa volume.

WATER BALANCE
POOL SHOP OR MA UAL WATER TESTI G
The Pool Lab ASP will automatically test your pool or spa water for ree Chlorine and pH
levels only. Other important water balance parameters such as Total Alkalinity, Calcium
Hardness, Combined Chlorine, and Stabilizer level will need to be regularly checked
manually with an appropriate test kit, or by taking a water sample to your local pool shop.
Your local pool shop should also be able to provide you with an appropriate water sample
bottle for this purpose. It is worth noting that many containers are not suitable for pool
water samples, as the materials used in the construction and the previous contents of the
container may drastically alter the results of the water test.
DO OT USE SOFT DRI K BOTTLES FOR WATER SAMPLES!
A soft drink bottle is a classic example of an inappropriate water sample container. The
water sample will tend to gradually take on the pH level of the previous contents, which is
generally quite acidic. Most soft drink bottles are also transparent, allowing UV light to
enter the container which will break down the chlorine in the sample much faster than
would occur in an opaque container.
Do not be alarmed if the ree Chlorine and pH results of a water test do not exactly match
the readings observed on the display. The ree Chlorine and pH levels of a water sample
are particularly sensitive to change in a small volume of water. Chlorine will break down
rapidly, especially when exposed to heat and/or sunlight. This process can also affect the
pH of the sample.
CHLORI E PRODUCTIO A D CO TROL
Free Chlorine Residu l
or your health and safety, a free chlorine residual of 1.0ppm to 3.0ppm must be
maintained.
Testing for chlorine levels is very important and should normally be performed on a daily
basis. The Pool Lab ASP achieves this better than any other method or device. Typically
(by default) the ASP will test the chlorine level three times per day and will control the
chlorine level by making adjustments to the chlorine output of your Pool Lab Chlorinator
with calculations based on water volume, chlorinator rating and previous demand.
The ability of the chlorine generator to maintain the correct chlorine level will depend on
the maximum output of the device (as rated in grams per hour), and the demand imposed
by bather load and other environmental factors.
10

High Chlorine Dem nd
In the event the chlorine demand is beyond the capability of the chlorine generator, then a
longer run time or occasional manual top-up dose with liquid chlorine may be all that is
required.
During periods of hot weather and high pool usage you should expect that the demand on
chlorine will be much higher than usual. Keep an eye on the free chlorine level, and have
some liquid chlorine available to use if the free chlorine level drops below 1.0ppm.
In addition to hot weather and high bather load, there are a few other common reasons
why chlorine demand might be higher than usual, these are:
1. Organic Debris – such as leaves, etc. in the water.
2. Low stabilizer level (applies to outdoor pools only).
3. High 'combined chlorine' level (explained on next page).
Chlorine St bilizer – Cy nuric Acid
or outdoor pools Pool Lab highly recommends using stabilizer (Cyanuric Acid) at a
concentration of between 50 – 80ppm. An outdoor pool exposed to sunlight will have
extremely high chlorine demand without sufficient stabilizer in the water. Never exceed
100ppm concentration of cyanuric acid, as this will prevent the chlorine from sanitizing the
water efficiently.
Combined Chlorine - Chlor mines
A common cause for unusually high chlorine demand is the presence of chloramines in the
pool water, detectable when a Total Chlorine test result is higher than a ree Chlorine test
result by greater than 1.0ppm. The difference between these two test results is known as
the “Combined Chlorine”. More advanced test kits will include the Total Chlorine test,
otherwise you will need to have your water tested professionally to check for this.
Chloramines are formed when free chlorine reacts with ammonia like compounds called
'amines', and this will build up over time. Chloramines are a poor disinfectant and also
reduce the disinfecting power of the free chlorine in the water. Chloramines are irritating
to the eyes and respitory system, and are responsible for the “chlorine smell” most
noticeable around heavily used indoor pools.
As a general rule Pool Lab recommend shock dosing your pool with liquid chlorine at least
once every swim season as this can significantly reduce chlorine demand and greatly
improves the disinfecting power of the free chlorine in the water. or pools with heavier
bather loads this may need to be done more often.
An accurate measurement of the pool volume and combined chlorine level is essential for
calculating the required amount of chlorine to perform the shock dose.
You should consult your loc l swimming pool profession ls for dvice on this
procedure, nd how often is ppropri te for your pool.
11

pH CO TROL A D ACID DELIVERY
'pH level' refers to a logarithmic scale from 0 to 14, where 0 represents the acidic end and
14 represents the alkaline end. A pH of 7 is neutral.
Generally a pH level between 7.2 – 7.6 is suitable for most pool types, however those
requiring a higher pH level will also require a higher chlorine residual.
Each pool finish and type has a specific range of pH that is suitable. You should seek
advice from your local pool professionals or your pool documentation to establish the
recommended pH for your pool.
Left unchecked, salt chlorination will over time increase the pH of your pool water to
around 8.4, and any addition of liquid chlorine can increase it further.
A high pH level will reduce the effectiveness of chlorine and can potentially cause scale on
the pool surfaces and equipment, and is irritating to the skin.
A low pH may cause the water to become corrosive, which can damage the pool surfaces
and equipment, and is also irritating to the skin.
The Pool Lab ASP will (by default) test the pH in your water three times per day, and will
automatically dose with dilute (16.5% maximum) Hydrochloric acid to maintain pH at the
desired value.
Total Alkalinity (T.A.)
The total alkalinity is a measurement of all the alkalis in your pool water. This includes
carbonates, bi-carbonates and hydroxides. It is measured in parts per million, or ppm.
These alkalis act as a “pH Buffer” which resist changes in the pH and help to keep the pH
level stable.
The most common and recommended way of raising the total alkalinity is by the addition of
sodium bi-carbonate (or bi-carbonate soda) to your pool water. Most pool shops will refer
to this as “pH Buffer”.
More advanced home test kits will include a test for total alkalinity, otherwise you will need
to have your water tested professionally to establish the correct dose to add.
The recommended T.A. for most pools is 80 – 120 ppm, depending on the interior finish.
Consult your local pool professionals or your pool documentation for the recommended
range for your pool.
Note: Reducing the total alkalinity is not as simple, and therefore over dosing should be
avoided. Consult your local pool professionals for advice on this if required.
12

Calcium Hardness
Calcium Hardness is a measurement of the level of calcium in the water, and may be
referred to as “water hardness”. It is measured in parts per million, or ppm.
This is often one of the most ignored parameters, yet just as important as the others.
The hardness of your pool water is very important in controlling scale and the corrosive
effects of water.
A low calcium level may cause pool water to become corrosive, even if the pH is within the
recommended range. Left unchecked this can damage the pool interior finish, and the
equipment.
A high calcium level may cause the pool water to deposit scale even if the pH is within the
recommended range. Scale build up on the pool surfaces can be unsightly and difficult to
remove, and it will also build up inside the pool equipment.
Scale can be particularly harmful to heating equipment as it can severely reduce the
efficiency of a heat exchange.
Scale can also build up on the plates inside your salt chlorinator cell. If left unchecked this
will damage the cell, and also risk voiding your warranty if it is not cleaned regularly.
Pool Lab Chlorinator cells feature a 'self-cleaning' design, but this will only work if your pH,
Total Alkalinity and Calcium Hardness parameters are within an acceptable range.
Generally a calcium hardness level between 100 – 200 ppm is recommended for most
pools. Consult your local pool professionals or your pool documentation for the
recommended range for your pool.
The calcium hardness level can be raised by the addition of calcium chloride to the water.
Pool shops usually referred to this as “Hardness Increaser” or similar. Always test the
water first before adding this as some water sources may already have significant
hardness depending on where it comes from.
In some cases the initial calcium hardness may be well above the recommended range,
and in these cases we recommend using the Langlier Index to determine an ideal pH
value that will prevent this water from scaling. See next page.
13

High Calcium (Hard) water sources – the Langlier Saturation Index
The Langlier Saturation Index (Si) is a relationship between the Calcium Hardness, Total
Alkalinity, pH and water temperature. When the water is balanced correctly, the Si value
should be somewhere between -0.2 and +0.2. A value lower than -0.2 indicates the water
is corrosive, and a value higher than +0.2 indicates the water is scaling.
If you are in a situation where the water source for the pool contains a higher level of
calcium than is recommended for you pool, then this index can be very useful. It will allow
you to find a pH value that will not be corrosive or scale forming, and this pH value will
generally be slightly lower than what would normally be recommended for your pool.
The following formula and reference chart can be used to find the current Si for your water.
You will need to know the pH level, Total Alkalinity, Calcium Hardness and Temperature of
your water.
Use the chart to determine the values for Ti, Ci, and Ai, and insert these values into the
formula, along with the measured pH value to determine your Si value.
If you get an Si value higher than +0.2, then your water is scaling. In this case you should
reduce the pH in your water by the value of Si to ensure your water is neither scaling or
corrosive.
Si = pH + Ti + Ci + Ai – 12.1

39 0.9 300 2.1 300 2.5
400 2.2 400 2.6
600 2.4 600 2.8
800 2.5 800 2.9
Example:
ph = 7.6, Temp = 24 (Ti = 0.6), C lcium = 400 (Ci = 2.2), Alk linity = 125 (Ai = 2.1)
Si = 7.6 + 0.6 + 2.2 + 2.1 – 12.1,
Si = +0.4, so the water is scaling.
In this case we would take 0.4 away from the measured pH to find the ideal pH is 7.2. A
pH value anywhere between 7.0 and 7.4 would be acceptable in this case.
14

WATER CIRCULATION
In general the total volume of swimming pool water should be turned over at least 1.5 to
2.0 times per day through the filtration system. Where traditional single speed pumps are
used, this is normally achieved within an 8 hour period.
With the introduction of energy efficient multi-speed and variable speed pumps it has
become more complicated than just running the pump for a certain amount of time.
It is important to ensure you are maintaining at least the minimum daily turnover of water.
If using a multi or variable speed pump at low speed, you may need to consult the pump
documentation to help determine the approximate flow rate you have.
If daily turnover is not maintained the chemical and sanitizer distribution in the water may
not be uniform, and water test samples may not be representative of the entire pool
volume. This can make chemical dosing inaccurate, and can increase the chance of
forming black-spot algae on your pool surfaces.
See examples below:
Tr dition l Fixed Speed Pool Pump
Pool Volume: 50,000 Litres
Pump Rated low: 210 LPM (Litres per minute)
Turnover Rate: approx. 4 hours. (238 minutes)
Time to turn over 1.5 x pool volume: approx. 6 hours (357 minutes)
Time to turn over 2.0 x pool volume: approx. 8 hours (476 minutes)
Energy efficient V ri ble Speed Pump, oper ting t pprox ½ flow r te
Pool Volume: 50,000 Litres
Pump Approximated low: 105 LPM (Litres per minute)
Turnover Rate: approx. 8 hours. (476 minutes)
Time to turn over 1.5 x pool volume: approx. 12 hours (714 minutes)
Time to turn over 2.0 x pool volume: approx. 16 hours (952 minutes)
This example illustrates that when you halve the flow rate, you effectively need to double
the filtration time.
When performing manual pH and chlorine tests for comparison with ASP results, always
obtain the sample as close as possible to the filtration system inlet – usually the skimmer
box. This place will be most representative of the readings acquired by the Pool Lab ASP.
Also ensure the displayed results are up-to-date by initiating a water test via the ASP
TOOLS menu.
15

CONSUMABLES
Reagent Bags
The Pool Lab ASP reagent bags contain 150mL of reagent each, which will last for
approximately 560 tests, or approximately 6 months at 3 tests per day. If the bags are
empty, then the ASP cannot perform water tests. In this case there will be no acid dosing,
and the chlorinator will continue to run based on previous demand.
NOTE: The Free Chlorine Reagent #1 has a limited shelf life and will slowly change
colour over time. Do not be concerned if this reagent has a magenta colour when you
install it. The reagent is considered expired only when it begins to turn brown and is no
longer transparent.
OTE: After installing new reagent bags, prime the reagent lines by either:
1. Cycle power O and back ON after changing reagent bags (clears test history)
2. Select PRIME REAGENT function from the menu system.
(a) Go to the MAIN MENU (press and hold VIEW for 3 seconds)
(b) Navigate to ASP TOOLS, press VIEW
(c) Navigate to REAGENTS, press VIEW
(d) Select PRIME REAGENTS, press VIEW
(e) Press VIEW once more to initiate the prime sequence.
16

Hydrochloric Acid – 16.5%
The Pool Lab ASP requires a reservoir of 16.5% hydrochloric acid for maintaining the pH
of the pool water. Hydrochloric acid can be purchased pre-mixed in 15 Litre or 20 Litre
drums at this strength, or you can dilute 33% acid by half with an equal amount of water.
(see instructions on next page).
Replace the cap of your acid drum with the fume stop cap and weight provided and set the
tube length so that the weight can reach the bottom of the drum.
IMPORTANT: When changing an acid drum that has been completely emptied you should
always cycle the power to your Pool Lab Chlorinator control box O then back ON again
after approximately 10 seconds. This will reset the acid feed algorithm and prevent the
chance of over-feeding on the first acid delivery.
To test the acid feed, or to prime the tubing:
1. Go to the MAIN MENU (press and hold VIEW for 3 seconds)
2. Navigate to ASP TOOLS and press VIEW
3. Navigate to ACID PRIME and press VIEW
4. Press VIEW to start acid pump (will run for 60 seconds)
5. Press BACK to stop acid pump.
6. Press BACK at least three times to exit the menu system.
Always wear appropriate protective clothing such as gloves, eye protection
and a suitable respirator (Type E) when handling hydrochloric acid or when
servicing the acid dosing system
17

Procedure to dilute 33% Hydrochloric Acid
The Pool Lab ASP has a peristaltic acid pump which is designed for use with 16.5%
Hydrochloric Acid. Most pool shops stock pre-diluted 16.5% Hydrochloric Acid which is
suitable for use, but if only 33% Hydrochloric Acid is available then you will need to dilute
this 1:1 with fresh water prior to use.
NOTE: While 16.5% Hydrochloric Acid will produce considerably less fumes than 33%
Hydrochloric Acid, the diluted acid is still VERY DANGEROUS and VERY CORROSIVE.
Always handle acid with due caution and care.
IMPORTA T: The use of undiluted 33% Hydrochloric acid (or any other unapproved acid
types) with your ool Lab peristaltic acid pump will void your ool Lab equipment
warranties and may cause large pH fluctuations in the pool water. This can lead to health
and safety issues and may cause damage to the pool surfaces or other equipment which
will not be covered by any warranty.
Prep r tion:
–This procedure must be performed outdoors in a well ventilated area
–This procedure must be performed in a location where an accidental acid spill will
not cause damage to property or equipment
–Re d section “Hydrochloric Acid (Muriatic Acid) Warnings” before proceeding
–Always wear appropriate protective clothing as shown below
–Where a SPA ONLY system exists, the total volume of diluted acid must be limited
to 5 Litres
–You will need either an empty Hydrochloric Acid Drum (5, 15 or 20 Litre), or a similar
container suitable for Hydrochloric Acid
–NEVER USE A CHLORINE DRUM OR ANY CONTAINER THAT HAS BEEN USED
OR CHEMICALS OTHER THAN HYDROCHLORIC ACID
–You will need a measuring jug or similar (for measuring water only), and a plastic
funnel suitable for hydrochloric acid
Procedure:
